What happens underwater to cause a tsunami?
The most common underwater causes of tsunami are earthquakes and volcanoes. The event causes a large column of water to be displaced and moved out from the source. See the related question about the causes of tsunami for more detail about this question and about other causes of tsunami that may not start underwater.
Do tsunamis have weather geologic or humans cause?
Tsunamis are primarily caused by underwater earthquakes, volcanic eruptions, or landslides which disturb the ocean floor. While weather conditions may influence the generation of tsunamis, such as in the case of typhoons or hurricanes, they are not the main cause. Human activities like underwater explosions or collapsing coastal structures can also trigger tsunamis but these are rarer occurrences compared to natural causes.
What magnitude generate tsunami?
Tsunamis can be generated by earthquakes, volcanic eruptions, or landslides underwater. The magnitude of the earthquake or the volume of material displaced by a volcanic eruption or landslide are important factors that determine the size and strength of the resulting tsunami.
Do all earthquakes cause damages?
No, not all earthquakes cause damages. The intensity of an earthquake, the distance from populated areas, and the quality of buildings and infrastructure in the area can all influence whether or not damages occur. Smaller earthquakes may not cause any significant damage, while larger earthquakes can result in widespread destruction.
Does the earth effect a tsunami?
Yes, but there are other factors that are just as significant. Earthquakes below 7.0 usually don't produce noticeable tsunamis. Larger earthquakes may or may not produce a tsunami, depending on the location, depth, type and orientation of the fault.
What ocean motion occurs from earthquakes?
Earthquakes in the ocean may cause tsunamis.
What is the name given to a seismic sea wave?
The term "seismic sea wave" has been found in geological and oceanographic texts, and typically is another term for a tsunami. Earthquakes at underwater subduction zones (where one tectonic plate moves beneath another) are the leading cause of tsunamis. Not all tsunamis are caused by earthquakes, however; other causes may include underwater volcanos, landslides, and underwater explosions (such as nuclear devices).
Is the motion of lithospheric plates a major cause of earthquakes?
It is the main cause of earthquakes. However you may get minor earthquakes due to volcanic activity or mass wasting events.
All faults will cause earthquakes?
It all depends on how big the fault is, bigger ones will cause bigger earthquakes, while smaller, or small ones may cause no earthquake at all.
A place that has man earthquakes?
Japan it gets very strong earthquakes and may cause a tsunami
What may two continental plate collide and cause?
Earthquakes
What happens underwater to cause a tsunami?

See the related question about the causes of tsunami for more detail about this question and about other causes of tsunami that may not start underwater.
What occurs when an earthquake happens?
Tectonic plates build up pressure and when the pressure gets to strong they collide. This causes the earth to rumble, which is an earthquake. Massive underwater earthquakes may cause tsunamis.
Which two natural disasters are commonly associated with the movement of tectonic plates?
Earthquakes and volcanoes. Earthquakes may also cause tsunami.
Are landslides accompanied by the occurrence of earthquakes?
The other way round. Landslides may be triggered by earthquakes but do not cause them.A large enough landslide will cause seismic activity that can be detected by seismometers however the trigger isn't the same as that found in earthquakes.
Do tsunamis have weather geologic or humans cause?
Tsunamis are primarily caused by underwater earthquakes, volcanic eruptions, or landslides which disturb the ocean floor. While weather conditions may influence the generation of tsunamis, such as in the case of typhoons or hurricanes, they are not the main cause. Human activities like underwater explosions or collapsing coastal structures can also trigger tsunamis but these are rarer occurrences compared to natural causes.
What other natural disasters occur during earthquakes?
Earthquakes can trigger landslides and can cause tsunami (tidal waves). Earthquakes also cause damage to infrastructure which can lead to fires (especially where gas pipelines are damaged) and may cause the spread of disease due to damage to water and sewer pipe lines.
